    The Powercrank Thread

    Relative, as in the relative contribution, went down slightly with increasing pedal powers. Absolute joint action powers went up with increased pedal power as you might recall from the figure in post 953. http://forum.cyclingnews.com/showpost.php?p=1573203&postcount=953

    The Powercrank Thread

    When net power goes up, all the joint-action powers go up as well (see Elmer et al. MSSE 2011 Joint-Specific Power Production during Submaximal and Maximal Cycling). When knee flexion power increases sufficiently, power during the leg flexion phase exceeds the power required to lift the limb...

    The pedaling technique thread

    Alex, Hamish, and Hugh: Have you guys noticed that this forum is always you rational guys vs. coapman and FrankDay? What percentage of the posts on this forum come from the five of you? 90+%? You, the rationals, try to debunk things but you just can't win. Every thread is a Tar Baby. Also, I...

    The Performance Enhancement Thread

    Hamish: In NZ do you guys, by any chance, get the American folk tales of "Uncle Remus"? They contain a lot of wisdom. I suggest you take 10min to watch this one about Tar Baby. See if you recognize any forum members. https://www.youtube.com/watch?v=u9svyIqwbOg Edit: Just in case it doesn't...

    The Powercrank Thread

    I should mention that I used to know what everyone ought to do. Before I went back to grad school I was a Masters National Champion and had coached riders to Masters National and Masters World titles. I knew EVERYTHING and wasn't reluctant to say so. Now, many years, 47 peer reviewed...

    The Powercrank Thread

    Thanks Hamish! With any luck I might get to meet you in person in NZ in December. The data that I have reported were calculated using standard inverse dynamic techniques. The raw data were recorded from a force measuring pedal and a motion capture system. It seems there is an interest in what...

    The Powercrank Thread

    Okay, I am just looking over comments that have been made since my post. Goodness, this is a congenial group! One of the points of contention seems to be related to my use of the word fix. My point was that since there is rarely negative muscular power there is nothing inherently wrong with...

    The Powercrank Thread

    Hi Hugh: Looks like I might be clear to post so I can try make a few contributions now. I know I'm years late to this party but perhaps I can make a few helpful points. As many posters have suggested, force or power delivered to the pedal at any instant represents a combination of muscular...
